Resumen
Objetivo

Habitualmente, las mediciones hemodinámicas se realizan con el paciente en decúbito supino y la cabecera de la cama a 0°. Nuestro objetivo ha sido evaluar la influencia de los cambios posturales en las mediciones hemodinámicas efectuadas a través de un catéter de arteria pulmonar, también llamado de Swan-Ganz.

Material y método

Estudio prospectivo, el mismo paciente es el grupo control y el grupo estudio. Se realizaron 3 mediciones consecutivas en cada paciente, comenzando en decúbito supino, posteriormente en decúbito lateral derecho y en decúbito lateral izquierdo. Antes de realizar las mediciones tras el cambio de postura, se dejó un período de 30 min de estabilización hemodinámica. Las variables a estudio, a parte de las demográficas, fueron: índice cardíaco, presión arteria pulmonar sistólica, presión arteria pulmonar diastólica, presión arteria pulmonar media, presión capilar pulmonar, presión de la aurícula derecha, presión arterial sistólica, presión arterial diastólica, presión arterial media y frecuencia cardíaca. Se incluyeron 28 pacientes.

Resultados

La media de edad de los pacientes fue de 62,05 años (57,05-67,05), el 78,6% fueron varones y tuvieron un NEMS medio de 42,4 (39,9-44,9). No encontramos diferencias en las mediciones hemodinámicas en las diferentes posturas.

Conclusiones

Los cambios posturales en pacientes estables, no influyen en las mediciones de las presiones y valores hemodinámicos.

Summary
Aim

Usually hemodynamic measures are done with the patient in dorsal decubitus and the bedside at 0 degrees. Our aim has been to evaluate the influence that postural changes has in the hemodynamic measures which were carried out with a pulmonary artery catheter, so as called Swan-Ganz.

Material and method

It’s a prospective study. The same patient is control group and study group. There were done tree consecutive measures in each patient. Firstly in dorsal decubitus, then right lateral decubitus and finally in left lateral decubitus. Before doing the measures after change of posture a thirty minutes period was left in order to stabilise the hemodynamical flow. The items of study were, a part of demographic ones, cardiac index, pulmonary artery systolic pressure, pulmonary artery diastolic pressure, pulmonary artery mean pressure, pulmonary artery occlusion pressure, right atrial pressure, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure and heart rate. 28 patients were included in the study.

Results

The age average was 62.5 years (27.05-67.05); a 78.6% were male. Who had a NEMS average of 42.4 (39.9-44.9). No difference was found between hemodynamic measures in the different postures.

Conclusions

Postural changes in stable patients have no influence in pressures and other hemodynamic variables measures.
